Maybe there's a device memory mapped in the lowmem region. Check using
tools like "lspci" or such. I can't think of another possibility right
now, so others might add...

BTW, it's a bit surprised me. Looking at the amount of your total RAM,
it should be all mapped in low mem. I wonder, why some of them are
shifted into high mem...

ANd the amount of committed_AS...that is really big compared to your
actual RAM, don't you agree?
